Dear PM-1 owners, I understand that it can be a very agonizing job reviewing a pair of headphones and not getting it right can leave you miserable. So here's my idea. Send a pair to Tyll. He'll have graphs and he's heard just about every pair of headphones made. He knows the ins and outs of them and explaining their sound comes as natural as Bob Barker telling you what prize you've won and understanding him is like hearing Bob tell you "you've won a brand new car!" you just get it.

I have tried the Oppo through a headphone amp and direct out of my iPhone, iMac and iPad. I set the headphone amp aside because it works perfectly unamped. It's plugged right into my iPhone's headphone jack right now.

This new headphone by OPPO is beginning to sound like an industry wide deal changer to me. Could it put headphone amp makers out of business?

Does anyone know where these headphones are manufactured? they sure look like Quality Control was a top priority. Looking forward to more comments.
